Specification of Letters Patent.

Application filed November 17, 1913. Serial No. 801,353.

Beit knownthat I, CHARLES H. J OCKMUS,

-' a ci-tizen'of the United States, residing at "plying. preheated air to the cylinder or Ansonia, county of New Haven, State of Connecticut, have invented an Improvement in Auxiliary. Air-Inlet Devices for' Internal-' Combustion Engines, 1s a specification.

. My inventlon relates to apparatus fore upcyl-v of which the following indersfof an internal combustion engine, has particular reference to such apparatus embodying a coil having communication with the cylinder. or cylinders and surround- .in the exhaust pipe of the en ine, said coil .turns one of ,which is provided upon its inner side with an elongated air inlet opening, 'jacent the exhaust pipe. .20

. flprovide means being formed of a plurality o An important ob ect ofthe invention is to acter, which is simple inconstruction, inex pensive to manufacture, highly efiicient in operation, and-durable.

vOther objects and advantages of the invention will be apparent durmg't-he course of the following. I

In the accompanying part of this specificatlon'and in which like numerals are employed to designate like Figure 1 is a side elevation of apparatus embodying the'invention; Fig. 2 is a central longitudinal section through a valve structure, parts being in elevation; Fig. 3 is an "enlarged edge elevation of a coil removed,

' pipe leading from 16 the horizontal I pipeinto which a pi e leads from each of seat .1 8-engaged.

and Fig. 4 is an enlarged side elevation of -the"same, parts being broken away..

10 rilenotes an engine which may' have a plurality of cylinders (not: shown, as the engine forms no portion of the invention), 11 a carburetor, 12 the portion of-the intake pipe leading from the carburetor, 13 the horizontal portion of the intake pipe, 14 an intake pipe leading from the horizontal portion to one of the cylinders, 15' an exhaust one of the cylinders and portion of the exhaust the cv inders.

. 17 denotes my novel regulator orvalve structure,

as a whole, and communicates with the portion of the intake pipe leading from the carburetor. j Within the regulatoror'valve'structure1s a; v

slide on a stem 20', the outer end of which tudinal adjustment in the head of the regulator. After adjustment the stem is locked 1n position by a set nut 22. At the inner end of the stem is'a head 23. A spring 24 bearing against the head and the pressure of the valve on the seat, which must be overcome to lift the valve. The regu lator is provided with a pet-cock 25 having a nipple to which a rubber tube 26 may be attached,

I supply heated air to the regulator or valve structure by means of a pipe 28 constitutin an important feature of the invention, w ichis connected to the regulator and the otherend of which is coiled about the exhaust pipe.

end of the coil is closed, as at 29 and that the end coil is cut away leaving an elongated opening or slot into the coil. As the coils themselves lie in close proximity to the'exhaust pipe, which is highly heated, and the opening is likewise contiguous to the exhaust pipe, it follows that the air drawn into pipe 28 and supplied to the regulator, must necessarily be highly heated. V

In operation, the valve 19 is opened or unseated by suction from the cylinder ,or cylinders of the engine. When this valve opens, air is drawn to the cylinder or cylinders through the pipe 28. This air is preheated before entering the cylinder or cylinders, the same first passing through the turns in the coiled portion of the pipe, which surround the exhaust-pipe. By having the end of the coil closed, at'2'9, all the air-enters through theslot 30, which is arranged upon allows of the proper free passage of the air path of travel'fo'r-the air,

the air. a

Having thus described my invention I claim? 4 I 1. Apparatus for suppl to the-cylinder olf .an in engine, embodying-a pipe having one adapted to be placed in'communication the cylinder ernal' combustion a d is threaded, as at 21, to adapt it for- 'longi-- valve causes It will be noted, see Figs. 3 and l, that the the inner side of the turn, whereby a. greater heating of the air is obtainable. This also,

the inner face of one of the coils, preferably 30 through which air is drawn ping preheated air surround the exhaust pipe of the engine,

" (he turn being provided upon its inner side with a longitudinal slot and the opposite end of the pipe being closed, substantially as described. v

2. Apparatus for supplying preheated air. to the cylinder of an internal combustion engine, embodying a pipe having one end.

thereof adapted to be placed in communication with the cylinder and its opposite end bent to form a coil including a plurality of turns to receive the exhaust pipe of the engine therein, the end turn being provided upon its inner side with a longitudinal slot and having its end closed, substantially as described.

3. Apparatus for supplying preheated air to the cylinder of an internal combustion engine, comprising a coil including a plu rality of turns to receive therethrough the exhaust -pipe of the engine, the end turn being provided upon its inner side with a longitudinal slot -and' having its outer end closed, and means to place the opposite end of the coil in communication with the interior of the cylinder, substantially as. de-' CHARLES H.1JOCKMUS.
